Non-Contact Vision Probe for Multi-Sensor System

RVP, Renishaw's vision measurement probe, is designed for use with the Revo five-axis measurement system on coordinate measuring machines (CMMs). The probe is said to increase the multi-sensor capability of Revo by adding non-contact inspection to the existing touch-trigger, high-speed tactile scanning and surface finish measurement capability of the system.

Thin sheet metal parts or components with large numbers of holes as small as 0.5 mm and parts which are not suited to tactile measurement can be fully inspected with the system. The probe is designed to improve throughput and CMM capability by utilizing the five-axis motion and variable positioning provided by the Revo head.

The system consists of a probe and a range of modules that are automatically interchangeable with other probe options available for Revo. Data from multiple sensors is automatically referenced to a common datum. According to the company, this flexibility means that the optimum tool can be selected to inspect a wide range of features on one CMM platform.

When using the system, part illumination is provided by integrated programmable LED lighting inside each module. Background feature enhancement is also available using backlighting combined with custom part fixturing. The system is managed by an I++ DME compliant interface and user functionality is provided by Renishaw's Modus metrology software. New Modus vision software capability includes RVP configuration, image processing with application-specific options and automatic image storage for review and further analysis.
